STOP AND WASTE COCK.

Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed June 9,1904. Serial No. 211,811.

To all 1077/0711, it may concern:

Be it known that I, DANIEL O. PoWERs, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Stop and Waste Cocks andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

My invention relates to interchangeable right andleft stop and wastecocks, and has for its object, first, convenience in interchanging theparts; second, the retaining of the stop in position; third, theprotection of the stop devices from dirt and the convenience inassembling the parts.

With the above objects in view my invention consists in the parts andcombination of parts hereinafter fully set forth and claimed.

In the drawings, Figure I is a view in ele vation, illustrating a stopand waste cock constructed according to my invention, show ing the partsconstituting the same separated and in relative position. Fig. II is acrosssectional view taken on line 2 2, Fig. I. Fig. III is a verticalsection taken through line 3 3, Fig. I. Fig. IV is a top plan view ofthe cock.

A represents the body or shell of the cock, having the usual connectionsa a and the At the upper portion of the bodyA is provided the flange A,with its cut-away portion forming stops 8 s. B represents the plug fitand ground into its seat within the body or shell A in the usual manner.This plug B has the ordinary or usual waterway B and the wastewayleading from one side thereof, as is usual.

The plug B is formed with a polygonal socket B for the reception of akey or handle C, and leading into this socket B is a screwthreadedorifice l), adapted to receive a screw. The plug B is also provided withholes or orifices O O, which are preferably drilled part way through theplug, as illustrated in Fig. II of the drawings, and are dis osed atright angles to each other. The ori ces O O are drilled or formed toloosely receive a pin P, which forms a stop for the plug. This pin Pprojects out from the'plug when properly seated, so that its end willengage the stop 8 s and allow the rotation of the plug B to the extentof the distance between the stops 3 s. The changing of the pin P fromthe hole to the hole 0 in the plug determines the direction of the flowof the waste from right to left, or vice versa, and it is with this partof the device that this invention especially appertains. The loosenessof the pin P in the orifice O or 0 allows it to be readily placed ineither orifice, according to requirements, and to be readily abstractedtherefrom without the use of tools; but in order to retain it when ithas been properly located I, provide the cap O, which fits over theupper end of the plug B and down around the upper end of the body orcasing of the plug A, as illustrated in Fig. III of the drawings. Thiscasing or cap C performs two functions. First, it acts to retain thepin]? in its proper relation to the plug as a stop in either of theholes O or O and at the same time forms a dirt guard or shield for thestop mechanism. The manner of securing this cap C in position is bymeans of the screw S, which passes through an orifice c in the cap C andfrom thence into the screw-threaded orifice b, where in case a handle isused, as illustrated in Fig. I, a screw S will impinge upon the same andhold. it in place.

In setting forth this invention I have shown and described mechanicaldetails and assemblage of parts as Iconsider them best adapted toperform their functions; but I do not wish, therefore, to be limited inthis invention, as they may be departed from in modifying theconstruction.

What I claim is In a stop-cock, a body or casing; a plug seated in thecasing and provided in its larger end with two holes arranged at orapproximately at a right angle to each other and extending inwardly asuitable distance from the peripheral surface of the plug; a pin looselyengaging one of the said holes and projecting a suitable distanceoutwardly beyond the peripheral surface of the plug; a suitablysupportedca'p surrounding the larger end of the plug and having a portionarranged to overlap the outer end of the pin in either position of theplug, and two stops formed on the 1 Signed at Cleveland, in the countyof Guycasing and spaced circumferentially 0f the l ahoga and State ofOhio, this 2d day of May,

pin-bearing portion of the plug, With the ar- 1904;

rangement of the parts such that one or the DANIEL C. POWERS. other stopis engaged by or adjacent the pin Witnesses:

other of its positions. R. I. ANDERSON.
